| // List of all lports to be used in the application | ||
| // A lport is defined by a netdev/queue ID pair, which is a socket containing a Rx/Tx ring pair. | ||
| // Each queue ID is assigned to a single socket or a socket is the lport defined by netdev/qid. | ||
| // Note: A netdev can be shared between lports as the qid is unique per lport | ||
| // If netdev is not defined or empty then it must be a virtual interface and not | ||

| // key/val - (R) The 'key' is the logical name e.g., 'eth0:0', 'eth1:0', ... to be used by the | ||
| // application to reference a lport. The 'val' object contains information about | ||
| // each lport. | ||
| // netdev - (R) The netdev device to be used, the part before the colon | ||
| // must reflect the netdev name | ||
| // pmd - (R) All PMDs have a name i.e., 'net_af_xdp', 'ring', ... | ||
| // qid - (R) Is the queue id to use for this lport, defined by ethtool command line | ||
